If you follow the book, the next paragraph on pg. 43 says:

The game will open, and you should be able to click on the cells and see 
how it works.

Well, so much for theory. . . When you click on a cell, a notifier 
window called the PreDebugWindow window appears with an error message! 
As depicted in Figure 2.12, it says MessageNotUnderstood: 

So I'm not sure it's supposed to work at that point. I think it's making 
a point about the Debugger or something.

Incidentally I don't know why it says "and do it", as "new openInWorld" 
seems to be enough.

You have another repository? OK.

At any rate this version seems to work alright. I always prefer to use a 
working example and see how it works. I wouldn't sweat the details to 
much. It sounds like you're getting the general idea of things.
